PEN-CLAMP FOR RULING--MACI-IINES.

Application filled April 12, 191.7.

To all whom t mag/concern.'

Beit known that l, ALBERT B Rorxnarngnn, a citizen of the United Statevs,iand a. resident ofA Harrisburg, inthe county of Dauphin and State of Pennsylvanimhave invented a certain new and useful Improvement in Pen-.Clamps for RulingrMachines, of which the following isa specification.

My present invention relates,particularly to the pen clamps ofy ruling machines, my object being theprovision .of a pen clamp by means fof which` pens may be clamped and released from the upper sideof the clamp in the machine, and by which their connection may be readily `made and rigidly maintainedl atk all times without danger of displacement.

' llithsthesevand other objects in mind, my invention resides in the features of construction, arrangement, and-operation to be presently describeil with respect to the accompanying drawing forming a part of this specilication, andv wherein- Figure 1 is a topplan view of my improved pen clamp with` the cover strip partly broken away;

Fig. 2 is a bottomplan view;

Fig. 3 is ap vertical longitudinal section through one endl of the clamp taken substantially on line 3 3 of Fig. l;

Fig. lis avertical cross section taken substantially on line 1 1 of Figdl, and

Fig. 5 is a perspective view of one end of the clamp illustrating the several parts in detached relation.

Referring now to these figures, my improved clamp consists of a body plate gen eially indicated at 10, having a reduced lengthwise rib 11 along its rear edge, by means of which it is clamped within a ruling machine, and provided with a relatively soft and preferably elastic facing 12 eXtendingalong andsecured to itslower face ad-` jacent and along its opposite edge, and `opposed by a lengthwise clamping strip l 13 having guide openings la adjacent the opposite ends thereof to receive guide pins 15 depending from the lower face` of the body plate 10 adjacent the opposite ends of the lattes i The upper and lower surfaces of thebody plate 10 are respectively provided with longitudinal grooves 16 and 17, the latter sub- Stantially semi-circular in cross section to Specification of Letters Patent.

partially receive a lengthwise shaft18 hav-` ing a longitudinally iiattened face 19, for a purpose to be presently brought out, the rounded ends 20 of which shaft `are journaled in bearings 21 carried by brackets 22 and 23 at the opposite ends of the body plate 10, ecah of which bracket has a lug 2e, as seenby reference to Figs. l and 3extending into the opposite ends of the upper rectangular groove 16 and secured thereto by fastening members 25.

The body plate alsohas vertical openings 26 at longitudinally spaced points communicating at their upper ends with the upper groovel for the reception of the T-shaped lever supports 27, as best` seen in Fig. t, the several heads of these supports being disw posed crosswise of and interfitting the uppergroove 16, as seen by reference to Fig. 1, andthe shanlrs thereof extending through the openings 26 with their lower apertured ends below the lower surface of the body plate 10 to receive and support the fulcrums 28 of a series of levers 29, the forward ends of which engage the lower surface of the clamping strip 13 at longitudinally spaced points, and the rear ends of which are engageable by the shaft 18 when the latter is partly turned to the position shown-in Fig. al.

` To this end the bearing bracket 23 has a.

vertically extending bearing 30, as best seen in Fig. 3, in whichlisjournalechaniupright` stem 31 having a wing nut 32 atits upper end and a worm-,3.3 at its lower end, the latter in engagement with a segmental worm wheel 34secured upon the adjacent end of the shaft 18.

Thus, when the shaft 18 is rota-ted to the position shown inF ig. 5, with its flattened face parallel to thelower face of the` body plate 10, pressure is released from the several levers 29 andi accordingly from the clamping strip 13, `so as Vto allow of removal,`

adjustment, and selected disposition of ruling pens A between the said clamping strip and the elastic face 12 ofthe body plate 10. Then `by rotation of the wing nut 32, which it will be noted, projects upwardly above one end of the body plate and is for this reason readily accessible, the shaftl8is .partially rotated so that it works in the nature of a clamp against the inner ends of the levers Q9 to force their forward outer ends into snug engagement with the clamping the desired degree of pressure against the several levers, so as to entirely obviate danger of accidental release in operation.

If it is so desired, and as shown in the several figures, the upper groove 16 of the body plate l0, may be housed by a cover strip 35 secured by suitable fasteninglmembers 36, the ends of which cover strip lap and conceal the lugs 24 of the end brackets 22 and 23, as plainly seen from Fig. 3.

I claim:

v1. A ruling pen clamp comprising a body plate having a compressible facing strip along its lower face and adjacent one edge, a clamping strip against said facing strip, a plurality of levers fulcrumed adjacent the lower surface of the body plate, each bearing at one end against the said clamping strip, a shaft journaled lengthwise of the lower face of the body plate to act against the opposite ends of said levers and having a longitudinal flattened face adjacent said ends of the several levers to release the latter, and means to rotate said shaft to engage and release the said levers.

2. A ruling pen clamp comprising a body plate having a movable clamping strip opposing its lower face adjacent one edge, a plurality of intermediately pivoted levers supported by the body plate, and disposed in longitudinally spaced relation therealong to engage the clamping strip at one oftheir ends, a shaft journaled along the body plate adjacent the opposite ends of said levers to engage the latter and provided with a flat face lengthwise thereof to release the levers,

and means to impart rotation to said shaft to engage and release said levers.

3. A ruling pen clamp comprising a body plate having a movable clamping strip opposing its lower face adjacent one edge, a plurality of intermediately pivoted levers supported by the body plate and disposed in longitudinally spaced relation therealong to engage thel clamping strip at one of their ends, a shaft journaled along the body plate adjacent the opposite ends of said levers to engage the latter and provided with a flat face lengthwise thereof to release the levers,

and means to impart rotation to said shaft to engage and release said levers, said means including a vertically rotatablerstem journaled at one end of the body plate and projecting thereabove andY having a worm at its lower end, and a worm wheel carried by the said shaft and engaged by the worm.

4. A ruling pen clamp consisting of a body plate having upper and lower longitudinal grooves, and a clamping strip opposing the lower face thereof along the inner edge, a shaft disposed in the lower longitudinal groove and having a lengthwise fiattened face to adapt the same for action as a cam, a pair of brackets secured to the ends of the body plate in which the ends of the said shaft are journaled, said body plate having openings extending therethrough and communicating with its upper groove, T-shaped supporting members extending through said openings with their upper headed ends in the upper groove and their lower ends projecting below the lower face of the body plate, a plurality of levers fulcrumed upon the lower endsof said supports, each of said levers having its forward end adjacent the clamping strip and its rear end adjacent the said shaft, and means for rotating the shaft for the purpose described.

5. A ruling pen clamp comprising a body plate having guide pins depending from its lower face adjacent one edge, a clamping strip having openings receiving the said guide pins, a plurality of intermediately pivoted levers supported by the body plate and engaging at one end the said clamping strip, and means engageable with the oppo` site ends of the several levers for simultaneously moving the same into and out of clamping engagement with the said clamp' ing strip.

6. A ruling pen clamp comprising a body plate having guide pins depending from its lower face adjacent one edge, a clamping strip having openings receiving the said guide pins, a plurality of intermediately pivoted levers supported by the body-plate and engaging at one end the said clamping strip, means engageable with the opposite ends of the several levers for simultaneously moving the same into Vand out of clamping engagement with the `said clamping'strip, said means including a shaft joui'naled on the body plate, and means for rotating the shaft consistingof a vertical stem at one end of the body plate having a screw connection with said shaft, whereby to lock the latter.

in adjusted position.
